First all-epoxy LH2 tank.
For want of a leg... A program was lost.
Remains being preserved for display at NM Museum of Space History
20th anniversary conference this August
Vertical or horizontal doesn't matter so much as operational efficiency
Vertical safer and simpler infrastructre

Rather crazy presentation claiming that all sorts of things are impact craters that aren't.
Then claiming all sorts of historical events are caused by impacts (for which there is no real evidence).
Using Bible stories as his historical reference.

CubeSats are good
Fireflies: one-way prospectors
Five targets per year by 2020

To clarify--Ben helped us test using one of our STEM booms as a sort of waveguide for sending WiFi signals, and I think the turn around was less than a week, but I lost count. Fun project, and Ben did a great job for us.

Interesting DSI says they support a COTS (SAA) methodology for NASA asteriod retrieval mission. PR already made statements supporting this.

Yeah, Tumlinson was clearly perplexed by the fact that the capture mission had gotten as far along as it has, and I think they are still figuring out how to properly respond.

Unreasonable Rocket - Paul Breed

Mainly business plans and concepts for a nanosat launcher this year
Viable but small market, good as a stepping stone
Build 15 chips with IMU/CPU
Tried canard guidance nose, lost authority at transonic
Went to thrust vector guidance, first crashed and burned
Next lost roll control at 200 kts
Added roll trim tabs, got to 400 kts under control
Going to use COTS GPS units (rated to 20 g) for future flights
Working on a small autopilot for fixed-wing UAVs
Asked to evaluate a cold fusion scheme by a "money guy"
All nanosats today are hitchhikers, not viable long-term
Much easier to do nanosats today
Very simple pressure fed launcher for 3U cubesats
Scheduled launches for $400k, custom launches for $600k
Launched at sea, from boat or plane
Reusability is trumped by low cost manufacturing
64-tube OTRAG-style with $1k per tube manufacturing cost (H2P2/Kerosene)
$125k vehicle cost
Cash flow positive after year 2
Looking for $2.5M
Fired first regen 3d-printed rocket in the world
Five staging events
Focus on the production process to improve reproducability

Shifting to cold fusion (LENR) stuff
Convinced LENR effect is real
But 95% of experiments fail
LENR wind tunnel with IR pyrometer to measure heat
Trying various stimulation methods

XCOR Aerospace - Jeff Greason

XCOR is as much a creation of Space Access as anything else
All started when he went to the the first one
EZ Rocket got down to $500 per flight
Need reliability before we can do the cool things
Reusability can work if and only if:
1. Capital cost is amortized over lifetime
2. Variable cost per flight is low
Suborbital is strategic
Lynx MECO ~100,000 ft
Glass top spacecraft
Three markets: people, payloads, and upper stages
Every year more and more nanosats
Lynx status: not done yet!
Propulsion wise in great shape
No fixed infrastructure (except ex-Marine Corp bunker)
Did Lynx engine test in partnership with Boeing
20 ms non-hypergol RCS
Avionics connected during engine test
Aerodynamics: done
Underside wing fences (right under fillets), allows for larger dihedral
Used the wind tunnel at Wright-Patterson
Cut away of the structure
Four pumps, four engines, each pair of pumps feeds a pair of engines
Started on airframe 2, which might fly first
Had some lessons learned from first airframe, wanted to try them immediately on second airframe
Buzz in the cockpit
Gear are mostly build, except retracts
Wing vendor change
Nose has been surprisingly difficult structurally
Need to close thermodynamic loop for pump/engine
Test LOX tank
In parallel LH2 pump program
Being paid to learn how to handle LH2 has been useful
Have to really reimagine how to handle LH2 with low infrastructure
Orbital vehicle: conception problems solved
Carrier aircraft plus two rocket stages, second is LH2
Goal is $1 million per person
Relocating to between Midland and Odessa
Low population density and big manufacturing base
Orbital vehicle: Carrier aircraft you can buy, both rocket stages reusable
Market is corporations paying to fly personnel to orbit (like offshore oil rigs)
There is a payload market (that he won't talk about) that is not comm sats
Move is because of California, just can't lease more space
Want the development and manufacturing in separate places
Florida will be serial production location
Looking for analog electronic engineers

Rand Simberg - Safe is Not An Option
We're not killing enough people in space
About 5% historical failure rate, comparable to bombers over Europe
The history of exploration is bloody
30,000 people die in cars every year
No such thing as a man-rated rocket
Orion launch abort doesn't real improve safety; half of abort still kill crew
Why does ISS need a lifeboat when the Scott-Amundsen doesn't have it
Really need redundancy on orbit
Stole a plot from Jon Goff: 5 deaths/day die from superbugs
Add one person to ISS could double science return
Have to be careful that NASA standards don't become industry standards
Baumgardener: FAA responsible for gondola safety, not jumper's safety
Extend morotorium indefinately
Kill SLS (which contributes nothing to safety) and fully fund commercial crew
Move OCST out of FAA and make it report directly SecDOT
Purge from language "human rating"
Purge unqualified word "safe"
Set value of astronaut life
Pillory anyone who says that "safety is the highest priority"
Send armadas to Mars
Act like space is actually important
5% of free divers die per year
All a mythology that accidents will kill space tourism
Grounded shuttles after accidents because the vehicles were too valuable to risk, not the crew
Risk of flying STS-1 lower with crew than without

Rand Simberg - Safe is Not An Option
Set value of astronaut life
Act like space is actually important

Yes! He's apparently writing a book on the topic (http://www.kickstarter.com/projects/1960236542/safe-is-not-an-option-our-futile-obsession-in-spac). From the executive sumnmary:

Quote

The implicit assignment of an infinite value to the life of a space farer, as has been the apparent and perhaps-unique default for decades, will inevitably result in a gross misallocation of resources and, paradoxically, actually increase the individual risk of death or injury. It is also a signal, regardless of how much money we spend on them, of how utterly unimportant and valueless we as a society believe that space accomplishments are, that we are unwilling to risk human life on them, compared to any other human endeavor such as commerce, mining, farming, construction, transport or even adventure seeking. If we are to open up space to humanity, this attitude must change.

Jim Muncy of PoliSpace
Recent legislation allowed all commercial rocket dealing with Russia
Trying to bring participants into indemnification
VG, XCOR, Grasshopper all fly by permits, not full license
This industry leaks like a sieve, so what secrets are you really keeping
NTSB is the one agency that can ignore ITAR
Better to share problems before you crash
The main safety pressure is cost-plus contractors afraid their gravy train will end
Really need industry standards, CSF may be the means to do this
But going to take an event to cause some companies wake up and support standards
Commercial imaging consolidation last year because they got too good and threatened established providers
There is nothing legally to stop a "a particular company" from launching a crew right now, and that terrifies some people in Congress. It's just money that stops them.
Gerst really held back NASA to let SpaceX solve the thruster problem, it's a respectful relationship
You can't force a customer to buy until they are ready to buy, NASA takes time

Panel Discussion: Post-LEO Policy - We know what to do for vastly improved access to Low Earth Orbit. What policies should support the move outward from there? Phil Chapman, Jeff Foust, Jim Muncy, Henry Vanderbilt

Outer space treaties are as socialist as they could be to get passed by US Senate
Most profitable part of space is beyond LEO: GEO
Biggest thing to do is create consciousness that this is about space settlement
Most politicians think in the Apollo frame
Inspiration Mars has gotten a positive reception, but then they are giving NASA money right now
Our number one national security rocket uses a Russian engine, but congressmen don't want to spend money on engine development
All they know astronauts going to point X
The problem of prizes is that they don't know which district the winner will be in
All small companies spread all over the place
You have to have independent technology programs
It is a feature, not a bug, that SLS has no new technology
NASA is so schizophrenic right now, they can't do anything
When an SLS contractor can force a company that they own 50% of to fire employees for suggesting that SLS is not perfect, there is a problem
